	```c++ template<class Key, class T, class Hash, class Pred, class Alloc> bool operator!=(const unordered_node_map<Key, T, Hash, Pred, Alloc>& x, const unordered_node_map<Key, T, Hash, Pred, Alloc>& y); ```	```c++ template<class key,="" class="" t,="" hash,="" pred,="" alloc=""> bool operator!=(const unordered_node_map<key, t,="" hash,="" pred,="" alloc="">& x, const unordered_node_map<key, t,="" hash,="" pred,="" alloc="">& y); ```</key,></key,></class>
	Return `false` if `x.size() == y.size()` and for every element in `x`, there is an element in `y` with the same key, with an equal value (using `operator==` to compare the value types).	若 `x.size() == y.size()` 且对于 `x` 中的每个元素，在 `y` 中均存在一个具有相同键且值相等（使用 `operator==` 比较值类型）的元素，则返回 `false`。
:1577	Notes:;; Behavior is undefined if the two containers don't have equivalent equality predicates.	注意：如果两个容器不具有等价的相等谓词，则行为未定义。
	Swap	交换
	```c++ template<class Key, class T, class Hash, class Pred, class Alloc> void swap(unordered_node_map<Key, T, Hash, Pred, Alloc>& x, unordered_node_map<Key, T, Hash, Pred, Alloc>& y) noexcept(noexcept(x.swap(y))); ```	```c++ template<class key,="" class="" t,="" hash,="" pred,="" alloc=""> void swap(unordered_node_map<key, t,="" hash,="" pred,="" alloc="">& x, unordered_node_map<key, t,="" hash,="" pred,="" alloc="">& y) noexcept(noexcept(x.swap(y))); ```</key,></key,></class>
	Swaps the contents of `x` and `y`.	交换 `x` 和 `y` 的内容。
:1589	If `Allocator::propagate_on_container_swap` is declared and `Allocator::propagate_on_container_swap::value` is `true` then the containers' allocators are swapped. Otherwise, swapping with unequal allocators results in undefined behavior.	如果 `Allocator::propagate_on_container_swap` 被声明且 `Allocator::propagate_on_container_swap::value` 为 `true`，则交换容器的分配器。否则，使用不相等的分配器进行交换将导致未定义行为。
	Effects:;; `x.swap(y)` Throws:;; Nothing unless `key_equal` or `hasher` throw on swapping.	效果：`x.swap(y)` 抛出：除非 `key_equal` 或 `hasher` 在交换时抛出异常，否则不抛出任何异常。

	Traverses the container `c` and removes all elements for which the supplied predicate returns `true`.	遍历容器 `c`，并移除所有使给定谓词返回 `true` 的元素。
	Returns:;; The number of erased elements. Notes:;; Equivalent to: + + ```c++ auto original_size = c.size(); for (auto i = c.begin(), last = c.end(); i != last; ) { if (pred(*i)) { i = c.erase(i); } else { ++i; } } return original_size - c.size(); ``` + Note that the references passed to `pred` are non-const.	返回：被擦除的元素数量。注意：等价于： ```c++ auto original_size = c.size(); for (auto i = c.begin(), last = c.end(); i != last; ) { if (pred(*i)) { i = c.erase(i); } else { ++i; } } return original_size - c.size(); ``` 注意，传递给 `pred` 的引用是非常量的。
